How to read these numbers
- These are estimates from a survey, not a count. The American Community Survey asks a sample of households. The ± figure is the Census Bureau’s margin of error: the true value is very likely within that range of the estimate. Small places have large margins.
- “Too imprecise to report” means the margin of error is at least half of the estimate, so printing the number would suggest accuracy that does not exist. A “rough guide only” note means the margin is a quarter to a half of the estimate.
- Property tax bill and home value are medians for owner-occupied homes. Half of the homes are above the figure and half below. A median bill is not the rate set by a city or town; the bill combines taxes levied by every local government that serves the home, such as the school district and county.
- “Calculated” rows are worked out by Untax the Roof from the Census figures above them. They compare two medians, so they describe the place, not a particular household.
- Missing is not zero. Where the Census Bureau publishes no figure, this page says so.

If property taxes go unpaid in Illinois
How it works. County tax sale of lien/certificate followed by circuit-court petition for tax deed
Excess sale money. Effective 2026 amendments create a surplus-equity fund. A former owner who loses property by issuance of a tax deed may seek an award based on property value less liens under 35 ILCS 200/21-302, subject to statutory rules
These rules are set by Illinois, not by Viola, so this section is the same for every place in the state. Last verified 2026-09-25. See the full Illinois entry with statute links.
